APWG Survey and deja vu all over again

As a participant in the APWG IPC, and a contributing researcher, I was pleased to see Dave Piscitello's APWG Web Vulnerabilities Survey Results and Analysis get some presscoverage as it went live in mid-June.
Rather than focus on the survey results (you can read those for yourself), I'd like to focus briefly on mitigation and concerns.
The Results and Analysis-compiled responses "suggest that web sites would benefit from broader implementation of preventative measures to mitigate known vulnerabilities and also from monitoring for anomalous behavior or suspicious traffic patterns that may indicate previously unseen or zero day attacks."
Given the broad scope of CMS platforms, forums, galleries, wikis, shopping carts, and others riding on top of the popular LAMP stack, the absence of such preventative measures and monitoring make for hacker nirvana.
Consider the problems shared servers introduce where vulnerabilities in any of the above-mentioned applications preloaded for…

toolsmith: RIPS - PHP static code analyzer

Image
In July's toolsmith I admit to the fact that I’ve often focused on run-time web application security assessment tools and paid absolutely no attention to static analysis tools.
For those of you in a similar boat, RIPS is a static source code analyzer for vulnerabilities in PHP. RIPS is written by Johannes Dahse who uses it when he audits PHP code, often during Capture The Flag contests.
To test RIPS in all it's glory, I compared its functionality to known finding from a vulnerability disclosure and advisory I posted for Linpha 1.3.4 in March 2009. Linpha 1.3.4 is a photo/image gallery (no longer supported or maintained) which exhibited cross-site request forgery (CSRF) and cross-site scripting (XSS) vulnerabilities during runtime analysis.
Specifically, input passed via GET to the imgid parameter is not properly sanitized by the image_resized_view.php script before being returned to the user. This vulnerability can be exploited to execute arbitrary HTML and JavaScript code in a u…
